This invention relates to windows, and more particularly to the type wherein the sashes are pivotally. hung to the supporting frames as distinguished from those in which 5 the sashes areljslidable. Amongst the objects of my invention are, to render opposite sides of pivoted sashes easilyaccessible for cleaning from within doors when the windows are swung open; and to insure maintenance ofthe sashes in any p'osition of opening against the. possibility of displacement underwind pressure, without necessitating use of special locking orlsecuring means for the latter purpose.

hinge mounting, which, as the windows are opened, causes the hinged edges of the sashes to recede to a substantial distance away from the contiguous rails ofthe' window frames with provision of. ample arm room in the interval; and which, although permitting ready opening or closingofthe windows, offers sufficient resistance against movement of the sashes under the conditions aforesa d.

. x Other objects and attendant advantages will be readily"apparentfrom the detailed description hereinafter of the typical embodiment of this invention shown in the drawings. Fig. I is a fragmentary view of the outside of a casement window equipped with my novel sash mounting.

and II. v I

Fig. V is a perspective view showing the two interpivoting members of the sash mounting; and, I

Fig. VI is a perspective view of a guide bar constituting one of the elements of the mounting. I

In these illustrations, the window frameis comprehensively designated by the numeral 10, and the swinging sash by the numeral 11,

both being constructed from suitable metal bar stock, in the present instance, ofZ cross section and so proportioned that their respective rails contact and interlap as shown in Fig. IV to insure weather tightness when the window is closed. The specific type of tion maybe used.

These ends I attain by provision of a novel Between the ear 15 and the bearing boss 19 .respectivelyof the members 12, 13 of each window structure chosen for convenience of illustration in the present connection is of course to be regarded as one of many others with which the sash mounting of my inven- As herein shown, thesash mounting com- 6 prises two interpivotingimembers 12, 13,

.(Fig. V) whereof the first embodies anaxially-apertured pivot ear 15 with a laterally offset depending flange 16 for attachment to the rail ll of the window sash 11, suitably spaced holes 1'? being provided in saidfiange to take securing screws 18, see'Fig. I. From Fig. V

I it will also be observed that the member 13 i has a bearing boss 19 with anaxial pivot pintle '20 to engage the aperture-in the ear 15, of thelmember-12J Thepart 13 furthemojre has an offset lateral extension 21 formed with a dove-tail groove 22 to engage a guide bar 23 (Fig. VI) of corresponding cross-section, se cured, as shown in Figs. I and III, along the 7 underside of the upper rail'web 10' of the. window frame 10 by screws 25. The sash 11 'is further connected to the window frame 10 beyond the hinge region- -by a projector link 26, having pivotal attachment at 27 with said sash, and at 28, with a fixed stud taking into the outerend of the guide bar 23. It is V to be understood that the parts just de'scribed are duplicated in reverse order at the bot- I tom of the window. Now since the'members 13 of the two hinge mountings employed with the window are confined to sliding movement along the bars 23, it will be apparent that, as the window sash l1 iso penedoutwardly to the I dot-and-dash line position of Fig. II, the pivoted edge of the said sash 11 is caused to Y recede or move away from the contiguous rail of the window frame 10 under action of the links 26. As a consequence, both sides of the sash 11 are rendered accessible for cleaning of its panes or lights from within doors.

For the purpose of preventing movement of thesash 11 under wind pressure when in open position, I make provision as follows:

sash mounting is interposed a friction washer 30, and a similar washer 31 applied for abutmentagainst the lower face of the ear aforesaid. The protruding end of the pintle I 20-is threaded for engagement by anut' 32 beneath which a splitspring washer. 33' is inserted. This arrangementobviously per-' between the contacting surfaces of I ingly resist pivotal movement of the sash 11 to a corresponding degree, the. adjusted presmits adjustment of the frictional ressure tlie parts 15, 19 and the Washers 30, 81 so as to yieldsure bein subsequently maintained under the action'of the spring washer 33. To insure thenut 32 against slipping after adjustment,

the latter is provided, as shown, with a numher of diametrical slots for selective registry with a transverse aperture in the pintle to recqive aloeking ,eotter pin 34L. The washers Y .including interpivoted members, each .of
